Exact Answer: 183 Years
Super Longevity is the ability to physically age much slower and live longer than that of normal humans and animals. Some super-powered beings like Hela Odinsdottir have stimulated healing constituents that are so robust that it prevents them from physically aging, hence giving them a sort of ageless immortality.
However, in Captain America’s case, this appeared to be limited. After retreating to the 1940s to live with Peggy Carter, he was an aged man by the time he reached 2023 again, where he would have been at least 185 years old.
Unlike Immortality, super longevity only reduces down super-powered individual’s physical aging process, whereas immortality usually stops super-powered individuals from physically aging and makes them practically unkillable.
How Long Would Captain America Live?
|Turning Points In Captain America’s Life||Age|
|Received Super-Serum||1941, 20 Years|
|Thawed Out Of Ice||2011, 27 Years (physically) 93 Years (with the frozen 66 years)|
|Handed Over His Shield||2023, 117 Years|
|Rest of his life||Approximately 183 Years|
In terms of his bodily age, Steve hands over his shield to Sam Wilson when he’s an agile 114 years old. But, he’s been alive for approximately 180 years. The Super Soldier Serum allows Captain to live longer than normal people. While it’s not impossible, 117 is a remarkably long life considering normal living standards.
Captain America’s biography, reflecting on the Marvel universe, the comic version of Steve Rogers was born on July 4th, 1920. He was given the Super-Serum in March 1941 when he was 20 years old. This is slightly different from the film version that states the day he was born.
Old Steve Rogers still had super soldier powers. The character didn’t age at a traditional rate, explaining why he didn’t look to get on the verge of death in Endgame despite his advanced age. Despite Steve’s continued strength, he felt an emotional got to step far away from the Captain America cape. Whether this is true within the 616 universes is up to speculation if super soldiers are immortal or not.
The Serum prevents individuals from aging due to the restoration of healthy cells. It is different from slowed aging seen in super soldier subjects. They might live as long as their DNA keeps reproducing itself without creating any errors. However, Rogers aged and rejuvenated recently. The answers could be that while the super-soldier formula is functioning within Rogers’s body, he’s immune to aging but not immortal.
Why Would Captain America Live That Long?
Here are some facts, as displayed by the Marvel Universe. Steve Rogers aka. Captain America was born on 4th July 1918. He bumped into the Arctic someday in 1945, he was 27, before being thawed out later after 66 years, in 2011. Summarising Captain America: The First Avenger, who is physically 27, but 93 technically. Considering his age as 27, because of the ice.
The major events of Endgame occurred in 2023, five years after Thanos snapped, and 12 years after Captain came out of the ice. So, Captain America is 27+12=39 years old ere he even goes near a machine, 93+12=105. Assuming that he goes back to round the exact point that he disappeared from his old life in 1945, he wouldn’t have left it an excessive amount later if he wanted to keep his relationship with Carter.
Steve had to wait for his rendezvous together with his teammates for around 78 years until 2023. 78+39=117. Or 78+105=183. “How can he look this good at 117 (or 183)?” Well, Chris Evans being a real-life example of divine greek god-like physic, Captain America’s genes were modified by the military within the 1940s to put him out as a super-soldier.
In the Marvel comics, the effect of the super-soldier serum on Captain’s aging is shown by what happens when it is counterpoised or brought out of him. In Captain America Vol 7 #21, an injury takes the serum out of him and leaves him as an aged man, at least 40 or 50 years older than he usually appears without it. So, it’s doing a lot of work to keep him ageless.
Regardless, whether or not he lived out his years in our certainty or another, he has wiled away many years by his return to the Endgame timeline again. The closing scene, which shows Steve and Peggy dancing to the song, ‘It’s Been A Long Long Time’ by Harry James And His Orchestra with Kitty Kallen, hints that he has reverted to the 1940s.
With the power of the Super-soldier serum, it won’t be hard for Marvel Studios to reveal why the old Steve Rogers was able to linger around despite his old age. If they indeed had any plans for him, it’s worth recording that he was considered to be dead, as evidenced in the tribute video presented at the beginning of Spider-Man: Far From Home so they have to take this into consideration if they’re planning to bring him back.
Perhaps Sam, Bruce, and Bucky solely decided to hold Captain America’s true fate secretive and let the world think that he perished during the battle with Thanos.
